Answer: 7
Step-by-step explanation:
Since squares have the same side lengths
then you need to find a number that multiplies twice that equals 49
7*7 = 49
Answer: Length of a side: 7 / Length of the diagonal: 9.9
Explanation:
Just square root 49, so it becomes 7. That's the side length. In order, to find the diagonal of the square, just use Pythagorean Theorem, a^2+b^2=c^2. Because it's a quadrilateral, all of the sides should equal 7. a^2 would be 7 and b^2 would be 7. 49+49=98. Square root 98 and you would get 9.899... That would be estimated to 9.9.
What is the sum of all integers $n$ that satisfy
$$-3n < 7n-20 < 3n~?$$
$($In other words, what is the sum of all integers $n$ that satisfy both of the inequalities
$$-3n<7n-20\text{~~and~~}7n-20<3n~?)$$
If you can't figure out the latex here is a screenshot ( in the comments)
Looks like the inequality is
-3n < 7n - 20 < 3n
Add 3n to each side:
0 < 10n - 20 < 6n
Solve the right inequality.
10n - 20 < 6n
Add -10n to both sides:
-20 < -4n
Divides both sides by -4:
5 > n
Now solve the left inequality, and take the intersection of the two solution intervals.
0 < 10n - 20
Add 20 to both sides:
20 < 10n
Divide both sides by 10:
2 < n
So 2 < n < 5. There are only 2 integers in this range (3 and 4), whose sum is 7.
Answer:
7
Step-by-step explanation:
We solve each of the two inequalities separately. To solve the first inequality, -3n<7n-20, we add 3n to both sides:
0<10n-20, then we add 20 to both sides to get
20<10n. Finally, dividing both sides by 10 gives 2<n, so n must be greater than 2.
For the second inequality, 7n-20<3n, we subtract 3n from both sides:
4n-20<0, then add 20 to both sides to get
4n<20. Finally, dividing both sides by 4 gives n<5, so n must be less than 5.
The only integers that are greater than 2 and less than 5 are 3 and 4. So, the sum of all possible integer values of n is 3+4=7.

Step-by-step explanation:
Victor baked 66 cookies with 11 scoops of flour. With 14 scoops of flour, how many cookies can Victor bake? Assume the relationship is directly proportional.
? cookies
Answer:
84 Cookies
Step-by-step explanation:
11/66= 14/x
11x=66*14
Solve for x
x=84
Answer:
84 cookies
Step-by-step explanation:
To solve this problem, we can use cross multiplication:
[tex]\frac{11}{66}=\frac{14}{x}[/tex]
66 * 14 = 924
11 * x = 11x
924 = 11x
924 ÷ 11 = 11x ÷ 11
84 = x
With 14 scoops of flour, Victor can bake 84 cookies.
Another way to solve this problem is to find how many cookies you can bake per cup of flour. To find this, divide the amount of cookies by the amount of cups of flour:
66 ÷ 11 = 6
You can make 6 cookies with 1 cup of flour.
So, to find how many cookies Victor can make with 14 cups, multiple 6 by 14:
6 * 14 = 84
Victor can make 84 cookies with 14 cups of flour.

Answer:
x < -8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
3 - (2x - 5) < -4(x + 2)
Step 2: Solve for x
Distribute: 3 - 2x + 5 < -4x - 8Combine like terms: -2x + 8 < -4x - 8Add 4x on both sides: 2x + 8 < -8Isolate x term: 2x < -16Isolate x: x < -8Here we see that any value x smaller than -8 would work as a solution in the inequality.

Edward deposited $6,500 into a savings account 4 years ago. The simple interest rate is 5%. How
much money did Edward earn in interest?
Substitute the values into the equation.
Interest=$• • years
Edward earned $ in interest.
Answer:
Edward earned $1300 interest in 4 years.
Step-by-step explanation:
Principal Amount = Initial Investment = $6500
Time t = 4 years
Interest rate r = 5% = 0.05 (it is taken in decimal i.e 5/100 = 0.05)
We need to find interest.
The formula used is: [tex]Interest= Principal\times r \times t[/tex]
Putting values and finding Interest
[tex]Interest= Principal\times r \times t\\Interest=6500\times 0.05 \times 4\\Interest= 1300[/tex]
So, the interest = $1300 in 4 years.
Edward earned $1300 interest in 4 years.
A prime number has two factors, itself and 1? *
Answer:
That is true. More information below.
Step-by-step explanation:
A prime number has to have only two factors: 1 and itself. 1 only has one factor (itself) so it is, as you were saying, neutral.

9.) 1/4 (8x - 20) = 2x-5

Answer:
5.) Associative Law
6.) Commutative Law
7.) Distributive Law
8.) Associative Law
9.) Distributive Law
10.)
Step-by-step explanation:
The associative law means that if all the arithmetic operations in an equation are the same, the position of the brackets do not matter and no matter which variables are associated, the result would still be the same.
The commutative law means that if all the arithmetic operations in an equation are the same, the position of the variables do not matter and no matter what order the variables are placed, the result would still be the same.
The distributive law means that whatever is outside of the bracket has to be multiplied into the variables in the bracket evenly. E.g. 1/4 (8x - 20) involves multiplying both 8x by 1/4 and 20 by 1/4.

Jane Dough sells her doughnuts for $0.15 more than what it costs her to make each doughnut. If you can buy 2 dozen doughnuts for $8.40, how much does it cost Jane to make each doughnut?
Answer: $0.20
Step-by-step explanation: $8.4 divided by the 24 or 2 dozen dougnuts she sells means she sell each donut for $0.35 and if we know that Jane Dough sells her doughnuts for $0.15 more than what it costs her to make each doughnut then $0.35 - $0.15 = $0.20 to make each donut

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
-16x-10>14-10x
hi can u please help me with this
Answer:
x < -4
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define inequality
-16x - 10 > 14 - 10x
Step 2: Solve for x
Add 16x to both sides: -10 > 14 + 6xSubtract 14 on both sides: -24 > 6xDivide 6 on both sides: -4 > xRewrite: x < -4Here we see that any value x that is less than -4 would work as a solution.
Answer:
Step-by-step explanation:
Let's solve your inequality step-by-step.
−16x−10>14−10x
Step 1: Simplify both sides of the inequality.
−16x−10>−10x+14
Step 2: Add 10x to both sides.
−16x−10+10x>−10x+14+10x
−6x−10>14
Step 3: Add 10 to both sides.
−6x−10+10>14+10
−6x>24
Step 4: Divide both sides by -6.
